* Reduced maintenance costs. Reducing the Linux load to only the functions needed for a given use also vastly simplifies software management and maintenance. These compact, finely tuned JeOS environments also allow applications to run more efficiently, with all components tested and optimized to run together. This is similar to how consumer equipment such as DVRs work. They are purpose-built with only the OS and application needed to perform a specific set of functions. Because the devices run on a trimmed-down OS, they are easier to set up, operate and maintain.
* Strengthened security. Mass customization of Linux is also an important factor for businesses needing to comply with regulations that require controlling access to sensitive data. By deploying a trimmed-down environment tailored to include only the applications, components and associated data needed by each user, organizations can build a foundation that helps prevent access by unauthorized users. Moreover, since JeOS contains fewer components, there are fewer attack vectors for hackers to exploit.
* Greater agility. Mass customization helps IT become more agile by reducing the time required to deploy new servers and speeding response to changing business needs. New use cases can be precisely configured and deployed to address market shifts. Additionally, these highly portable environments can be scaled up or down to rapidly respond to resource peaks and valleys.
In the future, virtually all computers will be tailored to meet an individual's unique profile, from the OS on up. The use of mass customized operating environments will proliferate as organizations realize the considerable financial, security and maintenance benefits.
Virtual appliances are one example of a mass customization success story, with IDC predicting the worldwide market for software and virtual appliances will reach $1.1 billion by 2012 worldwide. As demand for mass customization of Linux increases, we'll see businesses explore new use cases, from USB stick-based computers to cloud computing.
